This interactive map shows the point locations of reported vehicle crashes that occurred in 2021 from the VDOT dataset available here. You can zoom, pan, and click on features to reveal selected attributes in a popup window.
The kernel density layers shown here are estimates of the intensity of the underlying, unobserved process that produces an observed point pattern (i.e., the mapped location of reported vehicle accidents). It is useful for identifying areas where crashes are expected to occur more frequently.
